Blueprints Visual Scripting for Unreal Engine - Second Edition

By: Marcos Romero, Brenden Sewell

Overview of this book

Blueprints is the visual scripting system in Unreal Engine that enables programmers to create baseline systems and can be extended by designers. This book helps you explore all the features of the Blueprint Editor and guides you through using Variables, Macros, and Functions. You’ll also learn about object-oriented programming (OOP) and discover the Gameplay Framework. In addition to this, you’ll learn how Blueprint Communication allows one Blueprint to access information from another Blueprint. Later chapters will focus on building a fully functional game using a step-by-step approach. You’ll start with a basic first-person shooter (FPS) template, and each chapter will build on the prototype to create an increasingly complex and robust game experience. You’ll then progress from creating basic shooting mechanics to more complex systems, such as user interface elements and intelligent enemy behavior. The skills you will develop using Blueprints can also be employed in other gaming genres. In the concluding chapters, the book demonstrates how to use arrays, maps, enums, and vector operations. Finally, you’ll learn how to build a basic VR game. By the end of this book, you’ll have learned how to build a fully functional game and will have the skills required to develop an entertaining experience for your audience.

The Toolbar panel

The Toolbar panel is located at the top of the Blueprint Editor and contains some essential buttons for editing Blueprints:

The buttons are described as follows:

  • Compile: Converts the Blueprint script into a lower-level format that can be executed. That means a Blueprint must be compiled before running the game or the changes made may not be reflected. Click this button to compile the current...
